Can Your Home’s PEX Pipes Freeze?
Cross-linked polyethylene (PEX) pipes have become widely popular due to their flexibility. This material is great for retrofitting and is an inexpensive alternative to metal pipe options. PEX pipes are also touted for being freeze-resistant because of their ability to expand. While these pipes may need to reach a lower temperature to freeze, they can still burst and flood your home.
